PAPER-MACHINE.

SPECIFICATION forming part of Letters Patent No. 285,838, dated October2, 1883.

Application filed August 25, 1883. (No model.)

per-Machines, of which the following is a description sufficiently full,clear, and exact to enable any person skilled in the art or science towhich said invention appertains to make and use the same, referencebeing had to the accompanying drawings, forming a part of thisspecification, in which- Eigure l is anisometricalperspective View; Fig.2, a vertical transverse section, and Fig 3 a view of the product of themachine.

Like letters of referenceindicate corresponding parts in the differentfigures of the drawings.

Our invention relates to that class of machines which are employed inmaking laid paper; and it consists in a novel construction andarrangement of the parts, as hereinafter more fully set forth andclaimed, by which, a more effective article of this kind is producedthan is now in ordinary use. Q

In the drawings, A represents the body of the machine, 13 the exhaustioncylinder, and G the top roller. The cylinder is covered with wire-netting in the usual manner and j ournaled horizontally in the pulp box orbody A, the body, cylinder, and roller 0 being of the ordinaryconstruction and arranged and used in i the ordinary manner.

Mounted horizontally on the body A, and standing at right angles to theaxial line of the cylinder 13, there is a shaft, D, carrying,respectively, at its outer ends the disk E and miter-gear G, the diskcorresponding in diameter nearly with the width of the paper to beproduced. A short horizontally arranged shaft, H, carrying a fast andloose pulley, J, at its outer end and a small miter-gear, K, at itsinner end, is also mounted in the body A, the shaft H being arranged atright angles to the shaft D, and the gear K intermeshing with the gearGr. Disposed on the shaft D there is also a disk, L, provided around itsperiphery with a series of spool-holding spindles, a, carrying thespools m, the spools being secured on the spindles in any suitablemanner, so as to rotate freely. The disk E is provided around body A,preferably in such aposition as to be slightly submerged in the pulpliquid when the machine is in operation. This roller is arranged inparallelism with the cylinder B, against which it works and with whichit cooperates in making the paper. A spool, N, is placed near the disk Lon either side of the body A, (but one being shown,) and from thesespools the threads Z are led into the machine over the roller M andembedded in the pulp or paper in the same manner as the threads 9. Thethreads Z are designed to strengthen the fabric longitudinally andprevent it from being torn on the edge, and one or more may be employedon eitherside, as desired.

It will be obvious that either of the threads when followed through itscourse, will be found to be laid over the other threads 9 as it crossesthe fabric in one direction and under them as it crosses in the oppositedirection,

the rotation of the disks L E passing or laying the threads over eachother in this manner.

We do not confine ourselves to the employment of any special number ofthreads g, or to running the disks in unison with the cylinder, or inone direction only, as these may be varied without departing from thespirit of our invention; neither do we confine ourselves to the use ofthe edge threads, Z, as they may be omitted entirely; or two or more maybe used in place of one on either edge, if desired. In the use of ourimprovement the spools m are filled with the twine or thread to be used,the ends being carried through the guides d and inserted between theroller M and cylinder B in such a manner as to'be equidistant from eachother and distributed nearly the en tire length of the roller. Power isthen applied to the pulley f on'the shaft of the cylinder B, and also tothe pulley J on the shaft H,

the speed being such as to cause the disk L and 2 assess becomingembedded in and forming a part of the strip of paper it. The rotation ofthe disks L E causes the threads 9 to cross each other at h, so that thethreads are laid diagonally across the strip or web of paper t, as bestseen in Fig. 3, each thread crossing the web diagonally and being turnedinwardly near its edge, and recrossing it, as best shown at a: in Fig.3, thereby greatly strengthening the fabric and affording a secure holdfor tacks inserted in the bends at near the edge of the paper.

The paper or fabric, made as described, is designed more especially foruse in the manufacture of carpet-linings, but is well adapted for manyother purposes which will readily suggest themselves withoutparticularizing; but as we propose to make the paper or fabricdescribed, when in and of itself considered, the subject-matter of otherLetters Patent, we do not herein claim the same, broadly.

Having thus explained our invention, what we claim is the body A,cylinder B,

and roller M, in combination with means, substantially such asdescribed, for delivering the threads 9 and threads Z to said cylinderand roller, substantially as specified.

3. In a paper-making machine, the body A,

cylinder B, and roller M, in combination with means, substantially suchas described, for delivering the threads 9 to said cylinder and rollerand crossing and recrossing said threads in the pap er or fabric,substantially as set forth.

4. In a paper-making machine, the body A, cylinder B, and roller M, incombination with means, substantially such as described, for deliveringthe threads 9 to said cylinder and roller and crossing and recrossingsaid threads, and with means for delivering the threadsl to saidcylinder and roller in such manner that they will be embedded in theedges of the pa per or fabric, substantially as specified.

5. In a paper-making machine, the body A, cylinder B, and roller M, incombination with the disk L, provided with the spools m, the disk E,provided with the guides d and shaft D, combined and arranged to operatesubstan tially as set forth.

6. In a paper-making machine, the shaft D, carrying the spool-disk L,guide-disk E, and gear G, in combination with the gear K, shaft H,pulley J, cylinder B, roller M, and body A, substantially as shown anddescribed.

7. In a paper-making machine, the shaft D, carrying the spool-disk L,guide-disk E, and gear G, in combination with the gear K, shaft H,pulley J, cylinder B, roller M, spools N, and body A, substantially asset forth.
